I think it is, but it still has a lot of leeway... it might get redetected again in the GUI portion. I've done an install or two of Win2k and WinNT 4.0 on a laptop without a CD drive, and the only way to do that was to use a 2.5''>3.5'' adaptor to put it in a much newer and much larger desktop machine that was available to me... So between a 2.2ghz NF2 Athlon system and a P/100 ALi system, there might not be much difference, but there might be more differences between a HT P4 or some other MP system. But the APM/ACPI bits should be alright doing a ghosting of the text-mode phase.
